Subject: Mathematics (3 - 4) Title: Students Only! No Teachers AloudDescription: The students will be introduced to area and perimeter.The teacher will pose a real-life situation in which the students will have a chance to explore an actual section outside to determine the area and perimeter of a set location.

Subject: English Language Arts (4), or Mathematics (3 - 4), or Technology Education (3 - 5) Title: Abundant AreaDescription: This is an inquiry and technology-based lesson that allows students to discover the relationship between perimeter and area. Students apply problem-solving strategies to solve the real-life problem posed in this lesson. This lesson may easily be divided into sections and completed over several days if needed.

Subject: MathematicsTitle: Communicating about Mathematics Using Games: Playing Fraction TracksAdd BookmarkDescription: Mathematical games can foster mathematical communication as students explain and justify their moves to one another. In addition, games can motivate students and engage them in thinking about and applying concepts and skills. This e-example from Illuminations contains an interactive version of a game that can be used in the grades 3-5 classroom to support students' learning about fractions. e-Math Investigations are selected e-examples from the electronic version of the Principles and Standards of School Mathematics (PSSM). The e-examples are part of the electronic version of the PSSM document. Given their interactive nature and focused discussion tied to the PSSM document, the e-examples are natural companions to the i-Math investigations.Thinkfinity Partner: IlluminationsGrade Span: 3,4,5
